Abstract:
The present invention provides a probe card comprising a probe base, at least one impedance-matching probes, and a plurality of first probes. The probe base has a probing side and a tester side opposite to the probing side. Each impedance-matching probe has a probing part and a signal transmitting part electrically coupled to the probing part, wherein one end of the signal transmitting part is arranged at tester side, and the signal transmitting part has a central probing axis. Each first probe has a probing tip and a cantilever part coupled to the probing tip, wherein the cantilever part is coupled to the probe base and has a first central axis such that an included angle is formed between the central probing axis and the first central axis.
